RADIATOR.

Application filed March 6, 1926. Serial No. 92,896L

This invention relates to radiators of the type used to heat buildings.

:The radiators now in use are commonly provided with legs or feet that rest upon the floor to support the radiator in spaced relation to the floor, and the heating fluid is commonly conducted to and from the radiator by exposed pipes 'that extend upwardly through the floor to the points where they are connected to the radiator.

These radiator pipes are more or less unsightly, and they as well as the radiator supporting legs, constitute obstructions about which it is difficult to clean'or remove the dirt and dust.

An important feature of the present in vent-ion therefore resides in a novel construction whereby the radiator supporting legs are made hollow so that the fluid for heating the radiator may be supplied thereto As a result ofthis construction the radiator pipes are entirely con"- cealed and the'supporting legs are given a construction that is pleasing in appearance and about which the dirt and dust may-be much more easily removed than heretofore.

It is desirable to locate the valve which controls the flow of fluid through the radiator in an elevated position to increase its accessibility and it-has therefore been proposed heretofore to mount this valve 1n the upper part of a'radiator section, but in order to place the valve in thisposition it has been customary heretofore to provide a pipejoutside of the radiator which extends upwardly to the valve, and which is more or less unsightly; orthe heatingfluid has been led upwardly through the entire first section of a radiator to the valve, in which case the heating'fluid cannot be excluded from this first section by closing the valve.

' Another feature of the'present invention therefore resides in the'construction whereby the first'section of the radiator is provided with a separate conduitforrned in a portion thereof and which is adapted to conduct the heating fluid from a supply pipe to the valve at the upper end of the section.

. As a result of this construction the valve which illustrate one good practical form of the invention. In the drawings i w 3 Fig. 1 isa side elevation of a radiator constructed in accordance "with the present invention; i p p 5 Fig. 2 is partly an end View of. the left hand endof the radiator of Fig-1, and partly a sectional view taken on the line 22 of Fig. 1; and 1 i Fig. 3 is a sectional view taken on the line 33 ofFig. 2. .q

The radiator with which thepresent invention is associatedmay for the most part have any preferred or well known'construction, and the heating fluid for the radiator maybe steam or hotwater, as is usual.

The radiator shown consists of a series of connected intermediate heat. radiating secconstitutes the fluid inlet section and the section 11 the outlet secti0n,'but the *present invention is not necessarily limited in its use to radiators of the'type shown, having separate inlet and outlet conduits, since certain features of the invention may be emator section 12 is provided at its lower: end I with a downwardly extending boss or=nip-. ple 13 which is internally threaded to -re'- ceive the shorttube 14; that forms the up per part of a union. To'the short tube 14 is'secured the base leg v15-Which constitutes the lower portion of the union, and the portions 14 and 15 are secur'ed together by a union nut 16 which may have the usual or any preferred construction. The base leg 15 is provided with a flange portion 17 that rests on the floor and which flares outwardly in a direction transversely of the radiator, as shown, to provide a firm support for the radiator- The rounded outwardly flaring type of base shown is desirable as it is pleasv ing in appearance, and dirt anddust may be readily removed from around the same.

The lower end of the base leg 15 is preferably threaded as shown so that it may be screwed onto a supply pipe 18 that the heating fluid may pass from the supply pipe .18

upwardly through the conduit 19 to the radiator section 12. The construction is such that the base section 15 may be screwed onto the pipe 18 and then the radiator may be secured to this section by tightening the union nut 16.

The hollow leg at the opposite end of the radiator may besimilar in construction to the leg just described and serves to support the right-hand end of the radiator and also to form a conduit leading from the lower end of the section 11 to the return pipe 20.

The means just described for supporting aradiator and supplying the heating fluid to the same constitutes an extremely simple constructionwhich is inexpensive to construct and install, and by concealing the supply and return 'pipes the radiatoris given a more pleasing appearance and the floor around the supporting legs may be more easily a cleaned than heretofore.

The valve for controlling the supply of heating fluid tothe radiator may be located in various positions as desired, and in the construction shown the fluid control valve 21 is located near the upper end of the radi ator where it may be easily reached without stooping or leaning over. It is desirable that the valve 21 serve not only to cut off the supply of heating fluid'to the sections 10 and 1.1, but that'itserve also to cutoff the heatingifluid to'a portion of the'inlet sec tion 12. To this end, in accordance with the present invention, the section 12 is divided longitudinally by providing the same with the inner wall 22 that extendsupwardly from the inlet nipple 13 to form the conduit, 23. At the upper end of the conduit 23 is provided the transversely extending wall l24 with which the valve 21"cooperates, andthe arrangement is such that when this valve isopen theheating fluid may enter the portion 25 of the section 12 (see Fig. 3) .and'may pass through the bore 26 to theintermediate sections 10. The valve 21 may have anyusual or preferred construction and is operated by the handle 27. The returnradiator section 11 is preferably provided near-its lowere'nd-with a trap valve 28'which is constructed toretain steamwithin the radiator, while it will open to permit water to escape therefrom. These trap valves heretofore have been mounted in a valve casingoutside'of the radiatorwhere they form a connection between the radiator section and return pipe.

In. accordance with the present invention the radiator section 11 is provided with an interior wall 29 constructed to form a Yvalve seat and this wall isv so disposed within the radiator section that it forms a pocket within the section adapted to receive thev valve 28, the arrangement being such thatthe trap valve 28 is entirely housed within the radiator section" instead of being mounted out side of the section, as heretofore.

WVhat is claimed is:

1. A radiator, comprisingin a series of connected heat radiating sections, one of said sections being divided vertically by an interior wall to form a separate con duit at one side of'the'section, avertically combination,

disposed inlet port formed, centrally of the 6 lower end of said section, said. wall being bent at its lower end to form a curved passage communicating with the vertically disposed inlet-'- port, a. valve. at the upper portion of said conduit for controlling the passage of fluid from the conduit intoithe re: maining portion of the section, a hollow leg having a pedestal for supporting the section from the floor and provided with ayfluid passage leading to said port, and meansfor connecting the leg to a source of fluid supply. 2. A radiator, comprising in. combination, a series'of connected heat radiating sections, one of said sections being divided vertically by an interiorwall to form a separ'ateconleghaving a pedestal for supporting the section from the floor and provided with a fluid passage leading to said port, and-means for connecting the leg to a source of fluid supply.

In testimony whereof, I have signed my name to this specification. 1 THOMAS A. BIDDER.
